Why are these Leather Doctor® products the simple essentials when restoring an unwanted painted lambskin leather?
Purpose:
To remove non-original painted finishes that mask the natural beauty, softness, and breathability of lambskin leather.
Why it's necessary:
- Lambskin is ultra-fine and delicate, and many DIY or aftermarket paint applications form a suffocating, plasticky layer on its surface.
- These paints disrupt the leather’s ability to breathe, flex, and absorb conditioning agents.
- Deglazer 2.3 is a leather-safe system specially formulated to dissolve unwanted film-forming finishes without damaging the underlying leather grain.
- It restores the absorbency of the lambskin so it can properly undergo reconditioning in the next steps.
Mechanical scraping or harsh stripping chemicals can damage lambskin’s fine grain – Deglazer 2.3 safely softens ready to strip by gentle brushing.
2. Rinse 3.0 - Rinses Deglazing Residue
Purpose:
To remove suspended residue in tandem after deglazing.
Why it's necessary:
- It performs one primary responsibility - Stabilize the leather
- Cleaning loosens contamination - Rinse 3.0 removes and stabilize leather-safe.
Purpose:
To relax stiffened leather fibers and restore moisture before replenishing fat and oil.
Why it's necessary after deglazing:
The wet stripping process temporarily wets out the leather, and as it dries, the exposed structure may collapse and stiffen.Hydration is crucial to “plump up” the fibrous structure and restore its softness and receptiveness to fatliquoring.
Hydrator 3.3, a surfactant-based aqueous conditioner, lowers surface tension, allowing deeper penetration into the leather matrix.
It helps reduce fiber stress, wrinkling, and stiffness by re-aligning and lubricating the internal structure.
Think of Hydrator 3.3 as a "fiber relaxer" or a preconditioner that prepares the leather to accept the fat and oil that give it luxurious feel.
Purpose:
To restore the leather’s original fatliquor content (fat and oil) lost during deglazing and age.
Why it's essential before the leather dries again:
- Lambskin leather is originally infused with fatliquor during tanning to give it softness, flexibility, and resistance to cracking.
- When this fatliquor is lost — through stripping, drying, or age — the leather becomes brittle, noisy, and stiff.
- Fatliquor 5.0 restores the natural emulsion of fat (for softness) and oil (for flexibility) that lubricates the protein fibers.
- If leather is allowed to dry without replenishment, the fibers will stick together, resulting in a stiff and noisy leather.
Summary of Why This Sequence Matters:
| Step | Product | Role | Result |
| 1 | Deglazer 2.3 | Strip | Restores absorbency & breathability |
| 2 | Rinse 3.0 | Rinse | Residue free surface |
| 3 | Hydrator 3.3 | Relax | Prevents shrinkage & fiber stress |
| 4 | Fatliquor 5.0 | Replenish | Fullness with Suppleness |
By following this tannery-inspired sequence using Leather Doctor’s leather-safe system, lambskin leather is restored to its original softness, elegance, and luxury — without the suffocating aftermarket paint finish.

Instruction
1️⃣ Application & Agitation:
- Apply Deglazer 2.3 to Brush 9 and work on the paint.
- Gently agitate in a circular motion to loosen finishes and contaminants.
2️⃣ Extraction:
- Immediately extract the suspended residue with a lint free towel before the product dries.
- Eraser 4 helps in the removal process as needed.
- Repeat if necessary until the surface is clean.
- Apply Rinse 3.0 to rinse off suspended residue
- Immediately extract the suspended residue with a lint free towel before the product dries.
- Inspect with a finger slide for a healthy squeaky clean.
- Repeat if necessary until the surface is clean.
4️⃣ Hydrating:
- Apply Hydrator 3.3 to relax and plump the leather structure.
- Massage to soften leather especially if it feels stiff or dry after stripping.
- Foreign contamination is remove with towel extraction and ready for fatliquoring.
5️⃣ Fatliquoring:
- Immediately follow with Fatliquor 5.0 to replenish the essential fat and oil content, ensuring softness, strength, and suppleness.
- Leave the leather to dry naturally, well-stuffed (like a shoe tree or using grain or rice as stuffing for a handbag) to massage and keep its shape, then let it dry.
